W hen itis desired to lock the door so that it cannot be unlocked, even with the combination, ange sleeve G is pushed in by turning the screwj and moving set-screwj to the end J of slot J 2, (which slot is shown by dotted lines in Fig. 9,) and -fastening the flange-sleeve in that position with the 'setscrew, by means of which pin f is thrown to vand held in that part g of the slot in sleeve G shown in Fig. 8, when shoulder g2 raises up dog h, so that pin'fcannot comein contact with said dog, latch-bolt F thus becoming a lockbolt, spring 7L bearing against dog h and keeping the same thrown out and the door locked. )Vhen it is desired to use the lock with the combination, the flange-sleeve Gis pushed in by screw j, the iiange turning round to its proper position, so that set-screwj is near the end J3 of slot J2 and pin f is in that portion gJg of the slot in sleeve G, so that when'keys O are all in the position, as shown inA Fig. 2, knob A or K being turned without turning tumblers C and D, b does not turn sleeve G, while bolt F turns, causing pin f to come in contact with dog 71., throwingbolt II back and unlocking the door; but when keys O, or any one of said keys, are pushed in, the webs O and O2, being inserted in notches C of tumbler Gand D of tumbler D, cause said tumblers to turn with theknobs, and the sleeve of tumbler C, being connected with sleeve G by pin g, also turns said sleeve G, causing shoulder g to come in contact with and raise dog h before pin f comes in contact with said dog, thus preventing the bolt II from being thrown back, allowing the door to remain locked. Pin b is made stationary in shank B and inserted through slot o of tumbler Gand slot d of tumbler D and into hole a of knob A for the purpose of turning shank B with knob A and not allowing tumblers C and D to revolve around bolt F any farther than from one end to the other of said slots, and also to prevent knob A from being unscrewed. Spring d', (shown in Fig. 5,) attached at one extremity to tumbler D and at the other extremity to sleeve E by small pin c, and spring E', (shown in Fig. 7,) attached at one eXtremity to sleeve knob-plate E by spring attachment E2 and at the other extremity to the sleeve ot' tumbler C byl means of pin c', are for the purpose of keeping the notches D of tumblerD and C of tumbler C in line when the knobs are not being` turned, so that the webs of the keys may be inserted through said notches. Iinf on bolt F, striking against shoulder g5 of flange sleeve G, prevents the knobs from turning any farther in that direction. 'When it is desired to change the combination, the inside knob II is unscrewed from the bolt F sufficiently to allow knob A to be freed from the pin b', when said knob A can also be unscrewed from bolt F and the keys O turned over, reversing their position from that shown in Fig. 2, it becoming necessarythen to push the vkeys in to unlock the door. Keys O may also be'placed so that it may be necessary to push each alternate key in and the others out to unlock the door, or changed and made more or less complicated, according to the number of keys, which may be any number. Notches D2 of tumbler D are for the purpose of keeping the keys from being pushed in or out when the knobs are being turned.
